1. Accuracy depends on the number of satellites used, obstructions, satellite geometry (DOP), occupation
time, multipath effects, atmospheric conditions, baseline length, survey procedures and data quality.
2. 95% condence level.
3. 1 sigma
4. RTK initialization time based on unobstructed observing conditions, 7 satellites and a baseline length
of less than 5.0 km.
5. Specications for use with external batteries. If using internal batteries, operating range is –20°C to +55°C.
6. Storage temperature range is recommended to maintain shelf life of internal batteries.
7. Shock specications based on receiver without cables attached.
8. English, Spanish, Japanese, French, Chinese, Russian, Italian, Portuguese, Korean, General Tones.
